Kotal's palm uppercut is a special move? I just imagine that it's a normal. I'm also pretty sure that Sub-Zero doesn't have his ice clones at all unless you use Grandmaster. He just has ice ball and slide. But keep in mind that you can freeze more than once in a combo now, run combos, Crymomancer weapons will also add combo potential. Sure, just slide and ice ball isn't enough on it's own, but you get the variation specific moves also on top of them.
